UNITED STATES PATENT orrrcnf JOHN S. JACKSON, 01? CLINTON, ILLINOIS, ASSIGNOR OF ONE-HALF TO HENRY JACKSON, OF CLINTON, ILLINOIS.

CONTINUOUS-RAIL SWITCH.

To all whom it may concern:

Be it known that I, JOHN S.

Clinton, in the county of Dewitt and State of Illinois, have invented certain new and useful Improvements in Continuous-Rail Switches, of which the following is a specification.

This invention relates to certain improvements in and relating to continuous-rail railway switches; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what I now believe to be the preferred embodiment from among other formations and arrangements within the spirit and scope of the invention.

The invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forth hereinafter.

Referring to the accompanying drawingsFigure 1, is a top plan showing the switch set with the main track continuous. Fig. 2, is a plan showing the switch thrown to connect the siding and main track. Fig. 3, is a cross sectional view on the line 3'3, Fig. 1.

In the drawings, I show a break in the main track with the main track rails 1, separated a suitable distance to receive the interposed switch mechanism comprising track sections to bridge said break. The rails 2, of the branch or side track also terminate at this break and the switch mechanism is also provided with track sections to bridge the break between said branch track rails and the main track rails at one end of said break. The switch mechanism comprises a pair of similar rigidly connected parallel frogs 3, each throughout the length of its top face having a straight main track rail or section 30, and an inclined or angularly arranged branch track rail or section 31. The track section 30, is spaced laterally a distance from the track section 31, and said track sections are elevated above the intervening solid body 3, of the frog. The track section 30. is arranged along one longitudinal edge of the frog while the track section 31, is arranged along the 0pposite longitudinal edge of the frog. The track section 30, of one frog is arranged Specification of Letters Patent.

Application filed March 13, 1912.

Serial No. 683,586.

a j ,alongthe outer longitudinal side thereof, JACKSON, 21: citizen of the United States, residing at while said section 30, ofthe other frog is arranged along the inner longitudinal side thereof, and hence the switch is always pro-v vided with a guard rail whether the car wheels are passing over track sections 30, thereof or over the track sections 81. When the car wheels are passing along track sections 30, the inner track section 31, acts as a guard rail, and when the wheels are passing over track sections 31, the inner track section 30 acts as a guard rail.

The two frogs are rigidly secured together by bottom transverse or cross bars 4, bolted or otherwise secured thereto, and also by the central transverse cross bar 5, fixed thereto and at one end providing means for the attachment of the switch actuating connections 50, from any suitable switch throwing and locking stand not shown.

The base for the switch can be formed by a pair of wide ties or sleepers 6, and one or more intermediate ties 60, usually secured together by cross pieces 61. The two rigidly connected parallel spaced frogs are slidable on said base transversely of the track to and from positions wherein the track sections 30, register with the main track rails to establish continuity of the main track, and wherein the track sections 31, register with the main track rails at one end and the branch track rails at the other end to establish continuity between the branch and main track, as will be readily understood by those skilled in the art.

Suitable means are provided to guide the switch in its movements and to maintain the same down in proper position on its base and to limit the movement thereof. For instance,I show fixed transversely arranged guide bars 7, extending through transverse slots 70, in the opposite end portions of the frogs. These guide bars are rigidly secured at their extended ends 71, to the switch base and near their ends are bent down to form stop shoulders 72, to engage the switch and limit movement thereof in either direction.

This switch avoids the use of dangerous switch points and provides clear rail sections continuous with the track rails and thereby overcomes the danger of train derailment at switches.

The switch leaves no spaces or openings that can become so clogged by ice, snow or other obstructions as to prevent operation of the switch.

The switch is safe, efiicient and durable. W hen thrown to one position the other track sections thereof are entirely out of alinement and operative position.

It is evident that various changes, 1nodifi cations and variations might be resorted to without departing from the spirit and scope of the invention and hence I do not wish to limit myself to the exact disclosure hereof.

What I claim is A continuous rail switch comprising a pair of frogs secured together to bodily 15 slide transversely and having branch and main track sect-ions and transverse slots opening through their ends, a base for saio frogs, and guide bars fixed on said base and formed integral with stops limiting the sliding movement of said frogs.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN S. JACKSON.
